Thanks for the quick response, you're awesome :)
On the last one, I was trying to build a 19" 42U rack which was I guess quite detailed, and it didn't like me making things very (>80) tall. it's a special case for me, it's not a general problem because I'm probably using the wrong tool to do this, but since I was building my 1U servers and switch low poly models on that same scale, it made things harder to have a "1U" server 1.7 grid units high, and then have something . I'm working around it for now, so it's really a nice to have.
